Subjective Rating: 5/10 (Indifferent, ). Nothing ends up working at all, but it seemed very promising in the beginning. Some nice ideas - sadly, the complete lack of coherent storytelling means none of them have any relation to each other or to anything else. Strangely not-un-entertaining, considering the size of its problems.
Objective Rating (Average):
